We've been to NYC several times, but are now planning a trip for us and several of our friends. There will be 6 families (total of 25 people). We like to stay in Midtown and plan to see at least one show. Once we get there DH can do an excellent job as tour guide, but we'll need tickets for Empire State Building or Top of the Rock and things like that. Does anyone have suggestions for travel agencies or places we can get a good deal on packages. We'll need airfare (or we thought of taking AmTrak if it's a lot cheaper).
